The area of sealing land has increased by urban development after the Industrial Revolution. The sealing of land destructed the water circulation of city. The study of solution for this problem was executed to decrease out-flow rainwater. In this study, we investigated the status of rainwater permeable linear facilities and provide the management measure of it. The study site is Seoul, which is a representative city of Korea. The survey sites were divided into park and residential area. The contents of survey are structure, depth, materials of rainwater permeable linear facilities, and the quality of permeable water. In the result of this study, the rainwater permeable linear facilities were divided into 42 types. 30 types are in park area, and 12 types are in residential area. The permeable facilities are 12 types in 42 types. In the permeable facilities, 1 type is in residential area, and 11 types are in park area. In materials of rainwater permeable linear facilities, natural materials are 5 types and natural-artificial mixed materials are 7 types. The quality of permeable water is usually good. The constructing year and the ratio of rainwater permeable linear facilities is not related each other. As the result of this study, Seoul metropolitan government does not regard to rainwater permeable linear facilities. And so the management measure of rainwater permeable linear facilities is necessary for restoration of water circulation system in urban area.

Biotope Area Ratio ($BFF; BiotopFl{\"{a}}chenFaktor$) was developed in Berlin, Germany in 1990s and introduced to Korea in 1999. It is the ratio of the uncovered soil areas which have the natural circulating capability compared to whole development areas. This study seeks for alternative ways to increase Biotope Area Ratio of residential areas in the metropolitan areas of Korea by investigation on new housing developments. The study investigates four new towns including Seoul Eunpyung new town, Yongin Kusung district, Goyang Pungdong and Juyeopdong districts and Hwasung Dongtan district. The Biotope Area Ratio of study sites is between 23.51 % and 40.69%. This result is not relevant to land use conditions, such as the building-ta-land ratio, natural ground green area ratio. This ratio satisfies the minimum requirements of City of Seoul, except 2 sites. Considering that the study sites are relatively low density land use areas compared to Seoul's average, thus, a higher standards is necessary for new town housing complexes. Because Biotope Area Ratio includes artificial ground green area ratio, Biotope Area Ratio is possible can be increased with decreased natural ground green area ratio. And so, when Biotope Area Ratio is applied to new town development, it must go side by side with a definite natural ground green area ratio.
